| Summary : Limits runmode call rate per user
|
Description :
This module provides protection against a user calling a runmode too
frequently. A typical use-case might be a contact form that sends email.
You\'d like to allow your users to send you messages, but thousands of
messages from a single user would be a problem.
This module works by maintaining a database of hits to protected runmodes.
It then checks this database to determine if a new hit should be allowed
based on past activity by the user. The user\'s identity is, by default,
tied to login (via REMOTE_USER) or IP address (via REMOTE_IP) if login info
is not available. You may provide your own identity function via the
identity_callback() method.
To use this module you must create a table in your database with the
following schema (using MySQL-syntax, although other DBs may work as well
with minor alterations):
CREATE TABLE rate_limit_hits (
user_id VARCHAR(255) NOT NULL,
action VARCHAR(255) NOT NULL,
timestamp UNSIGNED INTEGER NOT NULL,
INDEX (user_id, action, timestamp)
);
You may feel free to vary the storage-type and size of user_id and action
to match your usage. For example, if your identity_callback() always
returns an integer you could make user_id an integer column.
This table should be periodically cleared of old data. Anything older than
the maximum timeframe being used can be safely deleted.
*IMPORTANT NOTE*: The protection offered by this module is not perfect.
Identifying a user on the internet is very hard and a sophisticated
attacker can work around these checks, by switching IPs or automating login
creation.
